Bug Dark spots on MLT

The mac version still shows black spots on highlights on MLT render, these spots only increase during time, no decrease.

Maybe it is a problem with the tonemapping function shooting the brightests highligts through the roof to black, or something else. here is an image.

The sky is physical sky with 3.2 intensity and there are portals behind those windows. the windows versions render the same scene without the black bits.

Hi lekonna

i would suggest to not increase intensity for physical sky and always sett it =1.000 ( the name of it say it all "physical sky " ;) meaning in the real world , you can not change the intensity of the sky/sun ... right ? ....... and KT physical sky works together with the generated sun by KT in a perfect balance of light intensity ( according to the time and location you have sett )

i know this is a common mistake increasing the sky intensity ..... but if you want to have more light in your room , just increase exposure ( like you would do with a real camera ) and/or adjust gamma if needed .....
by changing the physical sky intensity you are altering and destroying the accuracy of the sky/sun system

Greetings Patrick

on the quick network render test with the RC7.5 i didn't see any black spots but i'll check them later today with the mac only render.

What Lee is saying sounds to me exactly like a tonemapping problem with the dark pixels now propagating to ants because of maybe a newly added oversampling function or such ?

anyways i'll check later this evening.
